Welcome to Community!

Can these three simple words make a difference when you’re considering banks? We think so! We believe it speaks to an approach that puts you, and the things you value first, such as family, relationships and the financial goals you work so hard to achieve.

Not every bank puts you at the forefront, and you may know what it feels like to be lost in the system.

At OSB Community Bank, we pull everything together to make you feel valued. Personal attention, comprehensive deposit and loan products, the latest in online and mobile tech offerings and the long-lasting relationships that are formed when we all call the same place home.
